Dolphin on Android has had a bit of a checkered history since its inception. Users loved the idea of being able to take their favorite GameCube and Wii games on the go, but expectations and reality have never quite aligned. When Dolphin was first uploaded to the Play Store, developers tried to make it absolutely clear games wouldn't be playable, even going as far as calling it "Dolphin Emulator Alpha". Unfortunately, despite many warnings, many people got their hopes up the moment they saw Dolphin was on the appstore and were ready to play their favorite games, even if their device wasn't. While not everyone had false pretenses as to what should be possible, a lot of users blamed Dolphin for being poorly optimized rather than understanding that it wasn't even meant to run full speed yet.

The endless stream of poor ratings and angry comments eventually reached a breaking point and Dolphin was removed from the Play store mid 2016. That didn't mean development on Dolphin on Android had ceased, though. Instead, builds were provided on our download page, safely tucked away from the majority of users who may not understand the current state of the app.

On July 13th, 2008, Dolphin went open source, now just over ten years ago. While it could be easy to drift off into how much things have changed... there's one particular feature that has never quite lived up to the hype despite debuting that very same year - netplay.

As surprising as it may sound Dolphin Netplay has been around since the emulator went open source. For roughly a decade, users have tried their hand at taming the beast of synchronizing multiple instances of a GameCube and Wii despite their relative complexities. Netplay allows users to run the same instance of game on multiple computers by having two or more emulators in the exact same state, only transferring inputs between one another. By staying in lockstep like this, theoretically the emulators' states will never diverge assuming perfect determinism. This would allow people across the world to play a game together, even if it only featured local multiplayer on the console.

The problem has always been attaining that determinism. Back in the early days of netplay, it didn't especially matter what settings were used; Dolphin wasn't deterministic enough to stay in lockstep for very long. Then in the early days of the 3.0 era, it was finally possible to stay synced - if you were willing to sacrifice audio and performance. Early netplayers would hack up Dolphin to reduce requirements with 30 FPS hacks to Super Smash Bros. Melee, hacks to LLE audio to make it slow down less during attacks, and much more.

Despite the stutters and desyncs, some serious Melee players saw the potential and kept with the project. It wasn't until New-AX-HLE Audio (part 2) hit Dolphin that audio was both performant and deterministic enough to use in netplay. By the time Dolphin 4.0 rolled around, netplay had become a staple for Melee users and could be used by advanced users willing to suffer through some annoying quirks.

In the last few years, a focus has gone toward adding highly requested features to make netplay easier to use. Dolphin's STUN service allows some users who cannot port-forward play on netplay without issues, saves can be disabled to make synchronizing party games easier. But the one constant is that despite all these advances, simply getting netplay to work was a chore and crashes were common even if you did everything right.

Getting netplay into a more user-friendly state has been quite the process. In July, we saw some of the most drastic changes to netplay that we've seen in the past couple of years! Emulated Wii Remotes also saw huge usability improvements and some non-NVIDIA Android devices will finally be able to use Dolphin's Vulkan backend. If that wasn't enough, spycrab0 delivered some very big improvements to the DolphinQt GUI to give a new way to display your favorite games in the gamelist. Let's not delay any longer, please enjoy this month's Dolphin Progress Report.

On the Dolphin Forums, one of the more common questions that come up is "How come I can emulate this Wii game just fine but this GameCube game is slow?" While those more knowledgeable about the intricacies of emulation may roll their eyes, it does warrant some explanation. Usually when stepping down from a newer console emulator to an older console emulator, the minimum requirements for emulation drop significantly. While there are some exceptions when dealing with exceptionally obtuse hardware, that concern doesn't hold up here: The GameCube and Wii, ...
